Colgate Optic White Enamel White Luminous Mint Toothpaste features the maximum FDA-allowed sodium fluoride anticavity ingredient that helps fortify enamel’s weak spots for a strong white smile. Unlike ordinary toothpastes, it deeply whitens beyond surface stain removal (brushing twice daily for 4 weeks) while protecting and fortifying enamel. With its anticavity fluoride ingredients and a fresh mint flavor, it helps protect teeth from cavities and gives you fresh, clean breath.
